After Tyler is captured by crime boss Mother, Veronica, Roxie, and FBI agent Barnes fight to reunite the young boy with his mother, Eileen (Missi Pyle). In a classic bait-and-switch, they lure Barry into a trap and force him to make a deal with Mother that will hopefully ensure Tyler's safe return.

In the season finale, Veronica and Roxie must finally face-off against their old boss, Mother, and her lethal team. Can these assassins also save lives as they try to keep the stolen money out of Barry's hands and get Tyler back into his mother's arms?

While Veronica and Roxie relax on an island planning their retirements, it becomes painfully clear that Mother is still alive and is working with Eileen.
